Metal(Loid)s in Aquatic Products and Their Potential Health Risk

Aquatic products decrease environmental burdens and improve human health by supplying various essential nutrients, while their contamination with metal(loid)s could pose risks to humans through food chain. In this study, the concentrations, trophic magnification of multiple in aquatic were analyzed, including arsenic, cadmium, mercury, lead, cobalt, manganese, iron, copper, nickel zinc. The results showed that total concentrations marine foods from same sea area following order: seaweeds > shellfish cephalopods crustaceans saltwater fish freshwater fish. Arsenic speciation analysis indicated high arsenolipids detected lower organisms. maximum level organoarsenic seafood should be evaluated because potential toxicity arsenosugar metabolites. Weekly intake was far below recommended provisional tolerable weekly even excessive consumption products. hazard index above 1 for consumers, our also sharply decreased reducing ingestion cephalopods. study provided valuable guidance on general public.
